POURlNG-NOZZLE CAP FOR CANS.

SPECIFICATION forming part of Letters Patent No. 437,233, datedSeptember 30, 1890.

v Application filed May 9, 1890. Serial No. 351,152. (No model.)

To @ZZ whom it may concern.-

Be it known that I, EDWIN NORTON, a citizen of the United States,residing at Maywood, in the county of Cook and State of Illinois, haveinvented a new and useful Improvement in Pouring-Nozzle Caps for Cans,of which the following is a specification.

My invention relates to screw-cap pouringnozzles for cans.

I-Ieretofore the nozzle-caps of the kind to which my improvement moreparticularly relates have usually or frequently been made with acontinuous or solid cap-disk, to which the screw-nozzle is soldered orotherwise secured, a circular hole or opening being cut through thesolid cap-disk when the can is opened.

' The object of my improvement is to save the labor and expense incidentto soldering two parts of the nozzle-cap together, and at the same timeto provide a nozzle-cap of a simple, efficient, and durableconstruction, which may be opened without the usual inconvenientoperation of cutting out an opening through the tin, in which operationthe nozzle itself is often mutilated and destroyed.

I have discovered that a perfectly tight and efficient nozzle-closuremay be made by simply turning an internal flange around the opening in.or through the screw-nozzle and then driving a plain slip-cover ontothis ange, the parts being made slightly wedging vor tapering and to iitclosely and tightly when driven home. The flange of the slip-cover mayfit into the annular channel or groove between the body of thescrew-nozzle and its internal flange when said flange is made depending, so that it is perfectly protected from injury or externaliniiuence. The depending flange turned on the screw-nozzle, inconnection with the horizontal iiange j oiningthe body of the nozzle andits depending flange, gives great rigidity and firmness to the nozzleand makes a neat finish to the mouth thereof, as well as a seat forthescrew-cover. To open the nozzle, all that is necessary is simply toremove the screw-cover and the slip-cover. This may be done by drivingdown on the cover, where an inverted cover is used, until it is drivenoff the depending flange on which it fits, or by prying it out where theslip-cover is not inverted and no cutting is required, although it mightbe cut,-as heretofore, if desired.

My invention consists in the novel devices and .novel combinations ofparts and devices herein shown and described, and more particularlypointed out in the claims.

In the accompanying drawings, which form a part of this specication, andin which similar letters of reference indicate like parts, Figure l is acentral vertical sectional `view of a can embodying my invention. Fig. 2is a similar enlarged view of the nozzle-cap, and Fig. 3 shows amodified form.

In the drawings, A represents a can, which may be of any suitableconstruction.

d is the opening in the head A of the can, which is closed by the nozzlecap or disk B. The cap-disk B has the usual peripheral liange b to t thecap-groove a in the canhead A. This iiange b may preferably be hemmedwith a solder ring` h for soldering the same in place on the can-head.The capdisk B has a pouring-opening B', surrounding which it is providedwith an upturned screw-threaded iiange b2, which forms the body of thepouring-nozzle. The nozzle b2 is provided with an internal iiange b3,the same being united to the body of the nozzle by the intermediatehorizontal ange b4. The lower edge of the. depending flange b3 is madeslightly tapering or beveled inward at b5 to facilitate the reception ofthe driving slipcover C. The cover C hasa projecting flange c, the mouthor edge c of which is made slightly tapering or beveled, so that thiscover will fit with a wedging action upon the depending iiange b3. Thecover C may beinverted, as shown in Figs. l and'2, or fit inside theflange ha, as shown in Fig. 3. By reason of the tight wedging litbetween the cover C and the internal depending flange b3 of the nozzle,the cover C, when driven or pressed down on the flange b3, will make aperfectly liquid-tight closure.

D is the screw-cap, which lits upon the screw-threaded nozzle b2 of thecap-disk B.

To open the nozzle the screw-threaded cover D is first removed, and thenthe wedgingcover C is driven down into the can by press- IOO ing orstriking against the seam with a suitable instrument or pried out byinserting a suitable instrument between the offset iiange c2 on thecover and the nozzle b2.

By my improvement the pouring-cap nozzle can be not only rapidly andcheaply manufactured, as there is no soldering together of the partsrequired, but it may be also very conveniently opened,as no cutting ontof the tin is necessary.

I claim- 1. The combination of a screw-nozzle having a fiange to receivea slip-cover with an nternal sheet-metal slip-cover having a fiangefitting the fiange on said nozzle and forming a 1iquid-tigl1t jointtherewith by its frictional tit thereon and an external sciewcover,substantially as specified.

2.T11c combination, with a can, of a cap-disk fied.
